i To all whom it may concern:

B'e it known that I, WILLIAM O. CARR, a citizen ofthe UnitedStates,residing at Buffalo', in the county of Erie and State of New York,`haveinvented a certain new and useful Im roved Transportation System, ofwhich t e following is a specification. I

This invention relates to an improved underground system oftransportation, which is. preferably designed for use in carrying mails,packages,etc.

The object of the invention is to provideA a 4 very strong t andwcomparatively cheap conduit which 1s reinforced at intervals by metalreinforcements which are embedded in the body of `the conduit and haverojections extending into the interior of tiie conduit which serve assupports for the rails, constituting. the' track upon which the cartravels.

TheI invention also relates to certain details-of construction whichwill be hereinafter describedand claimed, reference being had t0` theaccompanying drawings in which a .preferred structureof the invention isshown.

Figure 1 is a transverse section through the underground tube of the imroved system, the section being taken t rough the concrete wall, thesupport for the ralls and the? railsalso4 showing a front elevation of`the car. Fig. 2 is a longitudinal section on a reduced scale through aportion of the underground tube of the improved system on line a a, Fi1showing a side elevation of the car in p ace upon the rails. Fig. 3 isan enlarged' fragmentary verticalsectionon line b b, 4 through one ofthe rail supports and a rail, showin the method of securing thel railthereto an supporting it therefrom. Fi 4 is a transverse section throughthe ra4 support showing a plan view of the rail fastening.` F' 5 1s afragmentary inside view of one o the rail supports and a rail securedthereto.

In referrin to the drawings in detail, like numerals designate likeparts. This improved system which is to be installed at a suitabledistance beneath the surface of the ground consists of a tube ofcircular, oblong or other desirable form in cross section, metalreinforcements for the said tube whichv are embedded at intervals in thetube body and rails which are supported from the ,metal reinforcements.

The body 1, of the tube is of concrete or' other suitable material andhas a series of metal reinforcements embedded therein and extendingcompletely around the same in a transverse direction and formingencircling loop reinforcements. These reinforcements are each preferablyconstructed in two sections 2 and 3 which are joined at the top andbottom res ectively by bolts 4 or other fasteners whic extend throughabutting lateral end flanges of the sections. v

- The sections about midway of their length are enlarged to form lateralinwardly extending members which project through the inner wall of theconcrete body into the interior of the tube and constitute supports towhich the rails are fastened. These su ports are preferably of the formshown in 3, 4 and 5 consisting of an inwardly extending portion-6, avertical flange 7 extending u ward from its inner end and a transverse yextending strengthening web, 8, which extends between about the middleof the flange and the inner surface of the reinforcement connecting atits bottom edge to the' portion 6, and serving as a stiffening andstrengthening bridge.

The rails 9 are preferably of angle form in cross section and arefastened to the supports by bolts 10 which pass through the verticalflanges 7 of the supports and the vertical portion of the rails.

A horizontal ledge 11 is formed on each sup ort which extends inwardlyfrom about the ower end of the flange 7 and extends beneath the verticalportion of the rail serving to support the same', see Fig. 3.

lnsulating'iber or similar non-conducting material is fitted between thevertical portion of the rail and the flange 7 and ledge 11 of thesupport'as shown at 12 in Fig. 3 and cach bolt 10 is also surrounded bya sleeve 13 of insulating material .which enlarges at one end to form awasher 14 between the nut of Athe bolt and the outer surface of thefiange 7, see Fig. 3.

The car adapted to travel on the rails is preferably of theconventionalA form described in my Patents Numbers 831,263 and 851,649granted September 18th 1906 and April 30th 1907, respectively to whichreference it to be had for a more extended description. This car is oflskeleton form having a frame 15 upon which a package carrier Q. einser16 is mounted end from which e series of indiyiduei muil boxes 17 eredetechebiysupported.

An electric motor i8 is inounted directly upon one or both exles 19 oithe csr end is driven by electric ower teken froml the under surface cithe orizontel ortion of the angie reiiby s suitebie trolley w eel 20.

rihe reiis ere elec'tricoily energized from eny -suitable source ofelectric power.

The chief edyenteges of this im roved system reside in the greetstrength lo structure obtained, coupled with moderete cost ofconstruction und the utilization of the loop reinforcements to supportthe rails.
